General description
The INFRA X20SR Speed Radar is designed for speed
measurements of different types of vehicles. Speeds up to 250 km/h
can be measured with 2 km/h resolution, both moving towards and
away from the unit.
The X20SR uses a high quality Doppler radar module, working in
the K-band (24.15GHz ISM Band). Dual channel techniques and
advanced signal processing makes it possible to distinguish between
movements toward and away from the unit, as well as filter out false
moving objects.
The X20SR continuously calculates speeds in both directions. At the
end of each interval it selects the direction seen the largest reflected
signal level to represent the interval. Movements toward the unit are
presented as positive values and movements away from the unit are
presented as negative values.
All quantities that are measured by your system are synchronized,
and can be viewed in any of the INFRA presentation systems.
The X20SR Speed Radar shall be connected to the INFRA Field
Monitoring System by any of the available INFRA Sensor Cables,
which:
Supplies the X20SR with electrical power
Handles the communication with the Datalogger, which is
the main unit in the INFRA Field Monitoring System.
Within INFRA Field Monitoring System it is possible to measure a
number of other quantities
simultaneously
with the speed
measurements, for example:
vibration (geophone) in one direction
vibration (geophone) in three directions
sound level
air blast
dust concentration
